Participants

Reaction Steps

A solution of N-carbobenzyloxyglycine (1.07 g, 5.00 mmol, 1.0 eq.) and (±)-[4-fluoro-2-(1,2,3,4-tetrahydro-isoquinolin-1-yl)-phenoxy]-acetic acid ethyl ester hydrochloride (1.93 g, 5.00 mmol, 1.0 eq.) in DMF (30 mL) was treated with 4-(dimethylamino)pyridine (2.44 g, 20.00 mmol, 4.0 eq.) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (1.44 g, 7.50 mmol, 1.5 eq.) and the resulting solution was stirred at r.t. for 18 hours. The reaction mixture was diluted with AcOEt (500 mL). The diluted solution was washed with 1N aq. HCl soln. (3×200 mL), sat. aq. NaHCO3 soln. (3×200 mL), sat. aq. NaCl soln. (1×200 mL), dried over MgSO4, and concentrated in vacuo. The crude product was purified by flash master (column: 100 g, flow: 35 mL/min, heptane to heptane+AcOEt) to yield the title product as a white foam.
